TL;DR : There is a ".bin" file in the BUILD directory that you can directly flash to the NUCLEO_F429ZI

mbed application for BLE server with STM32F429 and ST BLE shield and TI OPT 3001 light sensor

This application needs to be flashed into a NUCLEO_F429ZI running mbed firmware. It also needs an X-NUCLEO-IDB05A1 BLE shield running v7.2 or later firmware. The latest firmware can be found here: https://developer.mbed.org/teams/ST/code/BlueNRG-MS-Stack-Updater/

For the light sensor, I'm using a BOOSTXL-SENSORS breakout board from TI.

You'll also need a couple of jumpers, USB cables etc.

Please find the BLE_Client application under https://github.com/ashok-rao/BLE_Client_My_OPT3001 repo.

You can verify the output of this application either:

• on a serial terminal for your respective OS OR
• on a BLE enabled Android device with the Nordic nRF connect app

The application will print a few messages on the serial terminal and start reading the light sensor and show the readings with a 1sec delay.

If you are using the Nordic android app, you can scan for the "OPT3001" device and "connect" to it. Upon successful discovery of services, you can enable "notifications" and start getting the light sensor's data in hex.
